Usage Usage: psgetsid [\computer[,computer[,...] | @file] [-u username [-p password]]] [account|SID] If you want to see a computer's SID just pass the computer's name as a command-line argument. If you want to see a user's SID, name the account (e.g. "administrator") on the command-line and an optional computer name. Specify a user name if the account you are running from doesn't have administrative privileges on the computer you want to query. If you don't specify a password as an option PsGetSid will prompt you for one so that you can type it in without having it echoed to the display.

SID也就是安全標識符（Security Identifiers），是標識用戶、組和計算機帳戶的唯一的號碼。在第一次創建該帳戶時，將給網絡上的每一個帳戶發佈一個唯一的 SID。Windows 2000 中的內部進程將引用帳戶的 SID 而不是帳戶的用戶或組名。如果創建帳戶，再刪除帳戶，然後使用相同的用戶名創建另一個帳戶，則新帳戶將不具有授權給前一個帳戶的權力或權限，原因是該帳戶具有不同的 SID 號。安全標識符也被稱為安全 ID 或 SID。
